SNOW LOADINGAND DUMPING CART.

Specification of Letters Patent.

Patented July 31, 1906.

To all whom it may concern:

' Be it known that I, CARL G. OTTERSTEN, a citizen of the United States, residing in the borough of Brooklyn, city of New York, in the county of Kings and State of New York,

I have invented certaln new and useful Improvements in Snow Loading and-Dumping Carts, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings and to the reference characters marked thereon.

The object of this invention is to provide or produce a cart or vehicle more especially adapted for the loading and dumping of snow, which cart shall be amply strong and durable, of few and simple parts, easy to be operated, and which will be capable of self-loading as well as self-dumping, whereby snow may be economically and quickly gathered and carted away, especially from city streets and thoroughfares, without the necessity of stopping the cart in the street, as in the case of carts or wagons which require to be loaded by hand.

To accomplish all of the foregoing objects and to secure other and further advantages in the matters of manufacture or construction, operation, and use, my improvements involve certain new and useful arrangements or combinations of parts, peculiarities of construction, and principles of operation, as will be herein first fully described and then pointed out in the claims.

While my improved cart is chiefly de signed for use in gathering and removing snow from city streets, it will be apparent that it may be adopted for use in gathering and removing or dumping other materials or in any situation where its advantages may be utilized.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of my improved cart or vehicle, showing the front of the box lowered as when desired to take the load, the dumping position of the box being shown in dotted lines. Fig. 2 is a section and elevation on a plane passing longitudinally through the box, the front of the latter being shown in depressed position and the front plate or board shown as elevated, so as to open the front of the box to permit the snow or other material to pass in. Fig. 3 is a top or plan view and partial section of a fragment, showing the construction and arrangement of means for elevating and depressing the front of the box and locking it in any position.

and partial section of a fragment, showing the construction and arrangement of the axle, the manner of holding the spring thereon, and the manner of connecting the boxsupporting frame with the axle through the medium of the spring. Fig. 5 is a horizontal section and plan view of the front portion of the box, the view being taken on a plane through line 5 5 of Fig. 2, but showing the front plate or board in position to close the front of the box.

In all the figures like reference characters, wherever they are employed, indicate corresponding parts.

A and A are frame which supports the box and Which in turn is supported by the axle of the cart. These parts, as are, in fact, all the other parts, are made abundantly strong a d durable to withstand the severe uses to which they will be subjected. These. particular pieces are preferably made of T-iron, and they are bent down at the rear ends and supplied with suitable fittings to receive the hinge-rod Which connects the box with the supporting-frame and allows the former to be moved or tipped within the frame, and it is also supplied with fittings at proper points for the purpose .of mounting it upon the means by which it is connected with the axle of the cart.

At the front of the cart the side framepieces are connected by any suitable crosspiece, as B, on which the shaft or shafts is or are connected and the whifiietree secured. The cross-piece B affords a convenient footboard for the driver.

B represents a pole or shaft, which may be connected with the cross-piece B by any suitable means. A single pole is used when two draft-animals are employed, and in such case the weight upon the pole is usually transmitted to the collars of the harness on the animals, as will be readily understood; but two poles or shafts may be used, as when one draft-animal is employed or as when three are employed, and then the weight on the pole is preferably transmitted to the saddles of the harness, as is easily understood and not necessary to be graphically illustrated herein.

B represents any convenient form of whiffletree to be utilized for the ordinary purposes of such devices.

C represents the vehicle-box, the same be ing preferably made up of metal plates proptwo similar side pieces of the i Fig. 4 is a front elevation IlO erly riveted together, although it might be to side and nearly to the top this opening be ing arranged to be closedby a metal plate, as D, which is arranged to slide up and down between guides E E andF F. The pieces F and F are made of L-shaped iron and firmly secured to the box and bent back at their upper portions, as indicated in Fig. 2,

so as there to supply a support or rest for the plate D when the latter is elevated, in which position it is shown inFig. 2. In order to close the front of the box, it is only necessary to raise the plate to an upright position and permit itto descend in the guides provided for it or to crowd it down to place against the material which may obstruct the front opening in the box.

The rear of the box is provided with a hinged door G, the same bemg hinged at the ted lines in Fig. 1.

upperpart, as on a bolt G, and being arranged to be keyed fast at the lower part when closed, as by a removable key or keys at, entering suitable staples connected with the body of the box. The upper margin of the box being made of angle-iron, as indicated, is slightly cut away near the hinge and the door provided with a cross-piece b for abutting against the upper margin of the box when the door is turned up, as indicated in the dot It will be noted that the door when in this opened position extends above the top of the box, the purpose of this being that'when it is intended to dump the load a man can, if desirable, enter the .box to shovel out whatever portion of the contents may be necessary, he then having ample room to stand beneath the door without inconvenience. The box is hinged upon the lower ends of the frame, as upon a hinge-rod H, the same being secured to the bottom of the body in a substantial manner, as by blocks H, passing through fittings H on the ends of the frame-pieces and secured in place by suitable nuts or by other proper means. The hingerod H must sustain a portion of the weight of the load and must withstand the strains of the loading operation, and it is made amply strong for these purposes.

I I are shoes applied upon the front portion of the box-bottom and intended for contact with the roadway when the box is being loaded to prevent undue wear on the front edge of the bottom. Suitable eyes, as at a, may be conveniently applied in the shoes I at the sides of the box to facilitate attachment of a chain or other means which it may sometimes be desired to use to assist in drawing the box into a bank of snow or other material when the latter is unusually hard; but ordinarily it will not be necessary to employ this extra force in loading.

The front of the box is raised or lowered by mechanical means. In the form shown this means consists of a toothed are or segment K, one on each side, pivoted, as at cl, and actutated by an engaging pinion e, mounted upon a shaft f, fitted to receive a removable hand-crank It. The shaft f is also supplied with a ratchet-wheel f, and a pawl, as f is arranged to hold the ratchet-wheel at any desired point or to release it, as may be required.

The upper end of the are or segment K is supplied with a friction-roller i, which contacts with an inclined angle-piece L, bolted to the side of the box. When the arc or segment is raised by suitably turning the crank h, the roller 4; presses against the projecting portion of the angle-piece L, and thereby crowds the latter up, the box then turning upon the hinge-bolt H, as represented in Fi 1.

%Vhen it is desired to load the box, the plate D is raised and the front of the box lowered, so that its bottom edge contacts with the pavement or ground, as in Fig. 2. Then the cart is moved forward through the snow or material to be gathered and the box thus automatically loaded, after which the front is raised sufficiently to permit easy traveling and the front plate D closed. To dump the box, the front may be raised to any desired height after the door G has been swung open. Ordinarily the load will be discharged by its own gravity, the front of the box being further elevated by hand, if so desired. Lugs, as k Zr, serve for connecting the frame A with a suitable form of spring M, which may be employed.

The axle of the vehicle is represented at N, and it is made in one piece, extending across below the bottom of the box, thence up on each side, being provided with fittings for receiving the wheels, projections on each side, as at N N, to receive the yokes Z Z, by which the spring is secured in place, and a seat N for said spring.

The cart being constructed and arranged IIO substantially in accordance with the forego- I ing explanations will be found to admirably answer all the purposes or objects of the invention hereinbefore alluded to. It may be easily and quickly loaded, employing the power of the draft-animals for that purpose. It may be easily and quickly dumped, and it affords a capacious vehicle for carting away the material. A notable advantage of the use of the improved cart in city streets for removing snow is that it may move along with other vehicles, take its load without stopping, and move off with the load,in no way interfering with or impeding the usual traffic, which is an important consideration independent of the economy in the matter of loading.
